APM irule: remote login page needs referer

So the access policy refers to a remote login page which in this case is an app. That app needs to know which site you are coming from so that it can display some images and look/feel of that site. then it posts creds back to the access policy and is passed into the correct pool. Basically for the login page to act properly it needs to know that the request originated from www.mydaytonstore.com or www.mycincinnattistore.com and this the only way I can come up with to accomplish it. I had thought of setting it as session datatoo but I cant figure out how to get the session data out of the session and into the login app.?.

 

 

Thanks again for your help! It isnt easy fora noob.. =)
